NTI-tss Plus®
Anterior disclusion appliance for management of clenching-related headache symptoms.
The NTI-tss Plus is a custom anterior disclusion appliance that fits over the front teeth of either the upper or lower
arch. By separating the posterior teeth and canines during contact, the design aims to limit clenching intensity. It is used in clinician-directed care for migraine and tension-type headaches and may also be considered for selected
parafunctional conditions.
